I don't think you read too carefully about Metal or you'd know it's only for iOS and there are no known plans to bring it to OS X as they are completely different chipsets.
No, some things in Linux are "cutting edge" (as in the latest crap to try out here first). That's not the same thing as "state of the art". Art implies a near whimsical simplicity and ease of use that Linux has NEVER had. Linux is a PITA to use and having tried about 12 different versions in the past 12 years (not one a year, but sometimes 2-3 in one year), I think I can say that without feeling completely ignorant of the situation. Linux is about 15 years behind OS X in usability and that's saying a lot since OS X hasn't been around that long.
Yeah, if you don't ever install any software except from default repositories, it's a breeze to use something like Ubuntu on most setups. The problems start when you go to customize and add new software that you want to use that isn't on the repository or is the FAR more typical 3-4 versions behind on the repository because people working for free don't move too fast.... Then you get to see why repositories exist in the first place. You can pray that your distribution is supported by whatever vendor/person that is making it. OR you can use a generic build that may or may not work with your distribution depending on where your various resources and libraries, etc. are located exactly and if not, you can always jsut COMPILE COMPILE COMPILE it yourself like most software ten years ago in Linux. Yeah! That's a good way to spend a few hours to get Mame to work right on your machine! Woohoo. I know I've done it many times in the past. YOu get this feeling of accomplishment that you can actually run a tiny little utility that would have just been a "drag and forget" in OS X. And it's all due to the total and utter lack of compatibility between various Linux "flavors" and that's due to Linux being a mishmash of a thousand somewhat incompatible variations of "hacker happy happy joy joy". And having watched the Linux crowd for the past 14 years on and off, all I can say is they often ENJOYED being "elitist" and obtuse and hard to use and HATED developments like KDE and Ubuntu that tried to make it more mainstream. If you can't make Slackware work (and better yet in 2004 instead of 2014), you're not a real Linux user.
Yeah, I don't know if it's better than Windows Explorer. It's more of a step sideways in some respects, IMO. You might prefer one method over another, but frankly I preferred Dismaster II on my Amiga 3000 nearly twenty years ago to either one's default setup.
I knew it wouldn't be long before the first fan showed up to to tell us why it's a good move to get rid of identifying information and useful features. Obviously, NO ONE uses Firewire drives (I must imagine owning two myself, one FW400 and one FW800 since it's been a whole TWO YEARS since USB 3.0 came out and THREE since Thunderbolt that obviously FW800 drives are suddenly USELESS.
Frankly, I don't care if only one person still uses one. Why "break" something that isn't broken??? [I]The point is the OS is now LESS functional than before. [/I]
Red part I agree with. Its very stupid they would not have a differentiator between FireWire and USB so bad Apple in this respect.
The bolded bit? It's a beta, many things changed between the first DP and the latest one. They are still working on it, give it time. If Apple doesn't fix it however I will certainly not be supporting this stupid design made by them. FireWire is different from USB and this should show via the icons.
